A comparative evaluation of fracture resistance of endodontically treated premolar teeth reinforced with different prefabricated and custom-made fiber-reinforced post system with two different post lengths: An study.

Aims: The aim of this study is to determine the mean failure load for each postsystem and the relationship between post lengths with the mean failure loads.

Materials And Methods: Ninety single-rooted decoronated mandibular premolar teeth were endodontically treated and randomly assigned to three groups with respect to their post length (2/3 and ½ of the root length). The first two groups were randomly divided into four subgroups, restored with the following postsystem: polyethylene-woven fiber posts, glass fiber tape, prefabricated carbon, and glass fiber posts.

CRA Grid - A preliminary development and calibration of a paper-based objectivization of caries risk assessment in undergraduate dental education.

Context: Caries risk assessment (CRA) varies between students and faculty due to the subjectivity inherent in the process as well as in the critical thinking skills required for the processing of information.

Aims: The aim was to develop a paper-based, grid system, CRA-Grid, to objectivize and standardize risk assessment and to assess its rating agreement with the critical thinking process of the teachers.

Settings And Design: The CRA-Grid was developed and tested in a clinical study, in Indira Gandhi Institute of Dental Sciences, Puducherry.

Evaluation of the Shear Bond Strength of Composite Resin to Wet and Dry Enamel Using Dentin Bonding Agents Containing Various Solvents.

Introduction: Bonding of composite resin to dentin mandates a wet substrate whereas, enamel should be dry. This may not be easily achievable in intracoronal preparations where enamel and dentin are closely placed to each other. Therefore, Dentin Bonding Agents (DBA) are recommended for enamel and dentinal bonding, where enamel is also left moist.

Influence of different crosshead speeds on diametral tensile strength of a methacrylate based resin composite: An in-vitro study.

Aim: The aim was to evaluate the influence of different crosshead speeds on diametral tensile strength (DTS) of a resin composite material (Tetric N-Ceram).

Materials And Methods: The DTS of Tetric N-Ceram was evaluated using four different crosshead speeds 0.5 mm/min (DTS 1), 1 mm/min (DTS 2), 5 mm/min (DTS 3), 10 mm/min (DTS 4).

Clinical management of mid-root fracture in maxillary central incisors: case reports.

Management of mid-root fractures presents a formidable challenge for clinicians because of the difficulty of achieving a stable reunion of fracture fragments. This article presents two varied treatment options for mid-root fractures. A 15-year-old female reported an impact injury to the maxillary anterior teeth 2 days after its occurrence.
